HEADLIGI-II FOR LOGOMOTIIES.

Application filed Aprnae,

To all whom t may concern.'

Be it known that I, JOHN H. WHITING, citizen of the United States,residing at PunXsutawney, in the county of Jeierson and State ofPennsylvania, have invented certain new and useful Improvements inHeadlights forLocomotives, of which the following is a speoilication.

This invention relates to head lights, and more particularly to improvedmeans for insuring the projection of the raysof light upon the road-bedregardless of the curvature of the track.

The invention comprises novel means for automatically turning thehead-light by means of the side elevation of the locomotive or car as inrounding curves, the construction being such that the head-lights raysare directed along the road-bed at all times.

The invention consists of the combination with a rotatable head-light,of a. pendulum suitably connected to the headlight.

The invention also includes a governor de-y vice associated with thependulum to guard against unsteadiness or shock due to constantvibration.

The construction of the improvement will be fully described hereinafterin connection with the accompanying drawings which form a part of thisspecification, and its features of novelty will be defined in theappended claims. Y Y

In the drawings: Figure 1 is a side elevation of a head-light embodyingthe invention, Fig. 2 is a perspective view of the same, and Fig. 3 is adetail sectional view of the hollow pivotal mounting of the headlight.

The reference numeral l designates a support formed with an opening toreceive a journal and the depending pivotal stem 2 of the head-light 3,the latter being readily rotatable, and being supported upon co-actingdisks 4 and 5, between which anti-friction balls 6 are arranged torender the turning movement of the head-light as sensitivel as possible.Secured below the support 1 is ,an angle bracket 7 provided with abearing Speciicaton of Letters Patent. p

8 upon which isjournaled a pendulum rod 9 to which is attached a weightl0.

The stem 2 of the head-light is connected by an arm 11 with the upperend of the pendulum rod, and through .this connection the head-light isturned by the swinging ofv the pendulum. Y

As a means of guarding against shocks, and maintaining a steady light Iemploy a rod 12Vlooselv mounted upon, and near the upper end of thependulum rod 9 and also loosely journaled into the bracket 7 andcarrying an adjustable weight 13. This counterweight prevents shocks anduneven movements which might otherwise be caused by sudden movements ofthe pendulum.

As shown in Fig. 3 the pivotal mounting of the head-light is hollow foraccommodating the wires-14 in case electric lights are used with thehead-light.

Having fullv described my invention what I claim, and desire to secureby Letters Patl ent is 1. The combination with a support having anopening, a head-light having a pivotal support extending through saidopening, an angle bracket depending from said support. a pendulumsupported bv said bracket. a connection between the pendulum and thepivotal headlight support. and means for preventing shocks due to thesudden move ments of the pendulum.

2. The combina-tion with a support formedy with an opening. of arotatable head-light having a depending central pivot, an angle bracketsecured to said support, and prof vided with a bearing, a pendulumiournaled upon said bearing, an arm connecting said pendulum and thepivotal support of the head-light, a horizontally disposed rod supportedupon said vertical pendulum rod and guided by said bracket, and a weightsupported on said'rod.

3. The combination with a support formed with an opening. 'of arotatable head-light provided with a hollow pivotal support eX'- tendingthrough said opening, co-acting ball bearing disks between thehead-light and support, an .angle bracket secured to said support andprovided with a bearing, a In testimony whereof I alx my signa- Weghtedpendulum journaled upon said ture 1n the presence of two Witnesses.
